Abstract
Taking the Dachongkou River underpass project as the background,a three-dimensional numerical model was established using the finite element software FLAC 3D to analyze the deformation impact of the pipe jacking construction process on the existing river embankment,and the displacement characteristics of the upper existing river embankments during the construction process of new underpass were summarized.It was found that excavation vibration is the main factor causing deformation of river embankments.Further construction protection measures were designed for embankments,the safety factor of anti-skid stability of embankments was verified.The results meet the requirements of embankment regulations,which provide certain reference and reference for the safety evaluation of similar projects.关键词
